Thanks to everyone who posted.
It seems that barefoot may be the way to go with this mare but I will defintately consult my farrier to see what he thinks.
She is currently not on bute, but she is on ixosuprine which is a blood thinner to help circulation around the navicular bone.
I definitely want to read more up on the disease and check out some testimonials by owners who have horses with it.
I was wondering what is the difference between all natural barefoot trimming and other barefoot trimming?
I am growing to love this mare more and more each day because she is in a lot of pain at the moment, but she is so trusting and has the kindest eye about her. I am desperate to help her but the farrier is coming out soon to evaluate her so I hope things will start improving then. Thanks again!
(P.S. KANSAS_TWISTER: that is so horrible that that happened to the mare you had!! You must have felt so bad for her! I can't imagine having to watch a horse that I cared for go to slaughter! So sad!!
